Title of the thesis:Catalytic Oxidation of Furfural
Summary:The gradual reduction of fossil reserves and their negative impact on the environment forces humanity to look for alternative sources of use. One such alternative source is biomass. It is a renewable resource from which chemicals with the same properties as those made from fossil fuels can be obtained. Chemical made of renewable sources is furfural. The bachelor thesis focuses on the oxidation of furfural in the liquid phase in the presence of heterogeneous vanadium catalysts. The aim was to study the effect of these catalysts on the yields of the resulting organic acids with a focus on maleic acid. The reactions were carried out in stainless steel batch reactors in a temperature range of 80 - 120 ° C, an oxygen pressure of 0.4 - 1.0 MPa and a reaction time of 18 hours. The best result of the oxidation of furfural in the liquid phase was obtained using the 30 wt.% V2O5/SiO2 catalyst. In the presence of this catalyst, maleic acid was obtained by oxidation of furfural at the temperature of 120 ° C and the oxygen pressure of 0.8 MPa in a yield of 10.5% at 88.1% conversion of furfural. This work was supported by projects: grant VEGA 1/808/18 and APVV-17-0302.
Key words:furfural, oxidation, maleic acid, vanadium catalysts
